Description

Technical Field

[0001] This utility model relates to the technical field of rotary transformer manufacturing equipment, and more precisely to a hot air circulating oven for rotary transformer potting and curing. Background Technology

[0002] A rotary transformer consists of a stator and a rotor. The stator windings, acting as the primary winding, receive the excitation voltage, while the rotor windings, acting as the secondary winding, generate the induced voltage through electromagnetic coupling. Rotary transformers are widely used as precision angle, position, and speed detection devices in servo control systems, robotic systems, machine tools, and other technical fields.

[0003] Rotary transformers typically undergo potting, primarily to protect the coils, reduce noise, and improve overall stability. The potting material is usually epoxy resin or other materials with good insulation, thermal conductivity, and adhesion. After potting, curing is required, currently mostly done using tunnel curing ovens. However, tunnel curing ovens are large and energy-intensive, making them unsuitable for batch processing of small rotary transformers. Furthermore, the temperature control accuracy in tunnel curing ovens is relatively low, which can easily affect the insulation performance of the rotary transformer products. Existing technology also uses multi-layer ovens for curing, but these also suffer from large size, high energy consumption, and the inability to individually control temperature, which can lead to inconsistent curing results within a single batch.

[0004] In summary, there is a need in this field for an oven that is smaller, consumes less energy, and has higher temperature control accuracy, suitable for potting and curing small-volume rotary transformers. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a hot air circulating oven for curing adhesive in rotary transformers, which adopts a drawer-type structure combined with a drive device to reduce the overall size and energy consumption, and to precisely control the baking temperature.

[0006] To achieve the above objectives, this utility model provides a hot air circulating oven for curing adhesive on rotary transformers, comprising a box body and a drawer assembly. The box body has an internal cavity, and the drawer assembly includes a tray for placing the rotary transformer. The tray is detachably installed in the internal cavity. The drawer assembly also includes a drawer cover and a set of drive components. The drawer cover is installed at one end of the tray, and the drive components are combined with the box body and are pulsatorically connected to the drawer cover. The drive components drive the drawer cover and the tray to move.

[0007] Preferably, the front of the housing where the tray is mounted has a cover groove, and the cover groove is correspondingly provided with the drawer cover.

[0008] Preferably, the depth of the sealing groove is the same as the thickness of the drawer cover.

[0009] Preferably, a sealing ring is installed on the side of the drawer cover corresponding to the cover groove.

[0010] Preferably, a set of bearing slide rails is installed at the bottom of the carrier plate, and several sliders that are combined with the bearing slide rails are installed in the inner cavity.

[0011] Preferably, the drive assembly includes a cylinder and a drive rod. The cylinder is installed inside the housing, the drive rod is driven to extend and retract by the cylinder, and the end of the drive rod is connected to the drawer cover.

[0012] Preferably, an air inlet is installed on the back of the cabinet away from the drawer cover, the air inlet is connected to the inner cavity, and the air inlet is connected to an external air source.

[0013] Preferably, a connector is installed on the back of the cabinet away from the drawer cover. The connector is connected to a solenoid valve inside the cabinet. The solenoid valve is connected to a set of drive components. The connector is connected to an external power source.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 and Figure 2 As shown, this application discloses a hot air circulating oven for curing and potting adhesives in rotary transformers, comprising a housing 1 and a drawer assembly 2. The housing 1 has an inner cavity 10. The drawer assembly 2 includes a carrier tray 21 for placing the rotary transformer, which is detachably installed in the inner cavity 10. The drawer assembly 2 also includes a drawer cover 22 and a set of drive components 23. The drawer cover 22 is installed at the end of the carrier tray 21 located outside the inner cavity 10. The drive components 23 are installed in conjunction with the housing 1 and are connected to the drawer cover 22 in a transmission manner, driving the drawer cover 22 and the carrier tray 21 to move. The hot air circulating oven for curing and potting adhesives in rotary transformers is small in size, has low energy consumption, and its small internal space makes temperature control easier, resulting in uniform internal temperature and more precise temperature control. Multiple hot air circulating ovens for curing and potting adhesives in rotary transformers can be stacked and used, each with individual temperature control, ensuring the production yield of products in the same batch.

[0021] The front of the mounting tray 21 of the housing 1 has a sealing groove 12, which corresponds to the drawer cover 22. Preferably, the depth of the sealing groove 12 is the same as the thickness of the drawer cover 22. When the drawer cover 22 is inserted into the sealing groove 12, it seals the inner cavity 10, ensuring the baking effect. Furthermore, a sealing ring 221 is installed on the side of the drawer cover 22 corresponding to the sealing groove 12 to enhance the sealing effect.

[0022] A set of bearing slide rails 211 is installed at the bottom of the carrier 21, and several sliders that are combined with the bearing slide rails 211 are installed in the inner cavity 10 to ensure the smooth movement of the carrier 21.

[0023] The drive assembly 23 is preferably a cylinder assembly. The drive assembly 23 includes a cylinder 231 and a drive rod 232. The cylinder 231 is installed inside the housing 1. The drive rod 232 is driven to extend and retract by the cylinder 231. The end of the drive rod 232 is connected to the drawer cover 22. The cylinder 231 drives the drawer cover 22 and the tray 21 to move through the drive rod 232, thereby realizing the pull-out function.

[0024] An air inlet 11 is installed on the back of the cabinet 1 away from the drawer cover 22. The air inlet 11 is connected to the inner cavity 10 and to an external air source. A connector 13 is also installed on the back of the cabinet 1 away from the drawer cover 22. The connector 13 is connected to a solenoid valve 131 inside the cabinet 1. The solenoid valve 131 is connected to a set of drive components 23. The connector 13 is connected to an external power supply. The solenoid valve 131 controls the power supply status of the drive components 23.

[0025] Several handles 14 are installed on the outside of the box 1 to facilitate transportation and handling.

[0026] When using the hot air circulating oven for curing the rotary transformer, first turn on the external power and external air source; then preheat the oven to 150 degrees Celsius for 10 minutes; then the drive assembly drives the carrier plate to extend, place the coated rotary transformer on the carrier plate, and the drive assembly drives the carrier plate to retract into the inner cavity for baking; after baking, the oven will sound an alarm, and at the same time the drive assembly will drive the carrier plate to extend, so that the baked rotary transformer can be taken out.
